2026-10-23（UTC）——最后一天：上极限转向与暂停2026-10-23 (UTC) — the last day: the upper-limit turn and the pause
覆盖 UTC 2026-10-23 00:00–03:43（= EDT 2026-10-22 20:00–23:43）。Covers 2026-10-23 00:00–03:43 UTC (= 2026-10-22 20:00–23:43 EDT).
成果 / ResultsResults
- P65（红队复核前）：P55 几何（10–30 kpc 源环 / 150–300 kpc 背景，0.5–1.2 keV）下 96 个 P53 场、103,219 个随机孔的空位差分残余：blank-sky \(-18.6\%\) [\(-34.5, -7.5\)]，stowed \(-17.4\%\) [\(-33.6, -6.8\)]，场间标准差 \(\approx 59\%\)；曝光渐晕与粒子+天空双成分修正都不起作用；分半常数偏移不可迁移。P53 旧几何基线精确复现（\(-6.54 / -3.37\%\)）。状态：Provisional，未经独立复核（复核红队被暂停终止）。来源：cognition-os/07_REVISION_LOG.md R095。P65 (before red-team review): the empty-position differential residual at the P55 geometry (10–30 kpc source / 150–300 kpc background, 0.5–1.2 keV) over 96 P53 fields and 103,219 random apertures: blank-sky \(-18.6\%\) [\(-34.5, -7.5\)], stowed \(-17.4\%\) [\(-33.6, -6.8\)], field-to-field sd \(\approx 59\%\); vignetting and particle+sky two-component corrections do not help; a split-half constant offset does not transfer. The P53 old-geometry baseline is reproduced exactly (\(-6.54 / -3.37\%\)). Status: Provisional, not independently reviewed (the review red team was stopped by the pause). Source: cognition-os/07_REVISION_LOG.md R095.
- P66 重跑（放宽间隙后）：22 个 P58 目标场中的 12 个、1,785 个孔，空位双差分残余 \(+8.6\%\) [+2.0, +15.2]（面积 \(\alpha\)）、\(+12.3\%\) [+4.8, +16.4]（逐芯片曝光 \(\alpha\)）；场间散布 2.1 倍泊松（面积）、1.4 倍（曝光）。与 P65 的 \(-17\%\) 反号（分母不同：原始数据 vs blank-sky）。读法：内对外背景失配随场变化，量级 10–20%，不是单一常数。状态：Provisional。来源：R102。P66 rerun (after relaxing the clearance): on 12 of 22 P58 target fields, 1,785 apertures, the empty-position double-difference residual is \(+8.6\%\) [+2.0, +15.2] (area \(\alpha\)) and \(+12.3\%\) [+4.8, +16.4] (per-chip exposure \(\alpha\)); field scatter 2.1\(\times\) Poisson (area), 1.4\(\times\) (exposure). Opposite sign to P65's \(-17\%\) (different denominators: raw data vs blank-sky). Reading: the inner-versus-outer background mismatch is field-dependent at the 10–20% level, not a single offset. Status: Provisional. Source: R102.
- P68：把 P55 预报按 heli474 10–30 kpc 锚（\(b \approx 0.26\)）重新归一后，最佳单元 S/N 1.17（DD0，无系统误差）、0.85（DD2）、0.26（\(\approx 10\%\) 残余）、0.07（P65 包络）；10.5–11.5 仍是最佳质量档。含义：即使背景完美，档案 Chandra 叠加也测不到 eRASS1-heli474 水平的 10–30 kpc CGM。状态：Provisional（锚的置信区间含零）。来源：R103。P68: re-normalising P55's forecast to the heli474 10–30 kpc anchor (\(b \approx 0.26\)) gives best-cell S/N 1.17 (DD0, no systematics), 0.85 (DD2), 0.26 (\(\approx 10\%\) residual), 0.07 (P65 envelope); 10.5–11.5 remains the best mass bin. Implication: even with a perfect background, an archival Chandra stack cannot detect the 10–30 kpc CGM at the eRASS1-heli474 level. Status: Provisional (the anchor's CI includes zero). Source: R103.
- P69 可行性：eROSITA DR2（2026-07-31 公开）只有 eRASS:3 源目录与上限——没有可叠加的事件/图像/曝光图；DR3 预计 2028 下半年；只有 eRASS1 DR1 事件公开（本机已有）。Zhang 2024 eRASS:4 的精确复现NO-GO；eRASS1 He & Li 474 复现GO（本地 P21：泊松 7.16\(\sigma\) / 按星系自助 3.98\(\sigma\)，论文 7.4\(\sigma\)）。Chandra/CSC 2.1 覆盖：heli474 任意 62/474，\(\ge 80\%\) 30/474；wide4096 194/114。模型 XRB \(\approx 28\%\)（条件估计）。状态：Provisional。来源：R105；.agent/jobs/2026-10-22-P69-erosita-repro-chandra-improve/REPORT.luna.md。P69 feasibility: eROSITA DR2 (public 2026-07-31) carries only the eRASS:3 source catalogue and upper limits — no stackable events/images/exposure maps; DR3 is expected in the second half of 2028; only eRASS1 DR1 events are public (already on lang). The exact Zhang 2024 eRASS:4 reproduction is a NO-GO; the eRASS1 He & Li 474 reproduction is GO (local P21: Poisson 7.16\(\sigma\) / galaxy-bootstrap 3.98\(\sigma\), the paper 7.4\(\sigma\)). Chandra/CSC 2.1 coverage: heli474 62/474 any, 30/474 at \(\ge 80\%\); wide4096 194/114. Model XRB \(\approx 28\%\) (conditional estimate). Status: Provisional.

- 对 P58 试点 ObsID 3955 的复核红队：5 点全部 HOLDS——HISTORY 里 stowedbg=yes；逐芯片 BKGSCAL = 数据/stowed 9–12 keV 比值精确一致；曝光图单位 s、逐芯片、LIVETIME 匹配；删除的 62 个文件（0.628 GB）可再生（SHA256 一致）；径向行与独立 dmextract 匹配。状态：已分诊。来源：R097。The review red team on the P58 pilot ObsID 3955: HOLDS on all 5 points — stowedbg=yes in HISTORY; per-chip BKGSCAL equals the data/stowed 9–12 keV ratios exactly; exposure maps in s, per-chip, LIVETIME matches; the 62 deleted files (0.628 GB) are regenerable (SHA256 identical); radial rows match an independent dmextract. Status: triaged. Source: R097.
- P63：P60 的四个零门在 chandra_stack.py 副本上实现；41 个测试通过（29 新 + 12 P57）；植入 5% 共同偏移会触发门（\(Z \approx 27\)）。门代码审计红队对它 CHALLENGE（\(\sigma_{\rm total}\) 缺 V_common；门判定未在目标读取路径上强制执行）。修码任务 P67/P69 被暂停终止。状态：代码未定稿。来源：R099、R104。P63: P60's four null gates implemented on a copy of chandra_stack.py; 41 tests pass (29 new + 12 from P57); a planted 5% common offset trips the gate (\(Z \approx 27\)). A gate-code audit red team CHALLENGEs it (\(\sigma_{\rm total}\) lacks V_common; the gate decision is not enforced on the target-read paths). The fix jobs P67/P69 were stopped by the pause. Status: code not final. Source: R099, R104.
工作 / WorkWork
- P58（sol，Virgo）半 1 继续到 35 个已验证 ObsID（计划 213）；驱动在 ObsID 22445 下载截断处崩溃后由 sol 以 retry-once/skip 重启。P60 预注册被接受（R091：冻结表 sha256 6e47c5dc…，515 对；四个强制零门）。P58 (sol, Virgo) half 1 continued to 35 verified ObsIDs (213 planned); after the driver crashed on a truncated download at ObsID 22445, sol restarted it with retry-once/skip. The P60 pre-registration was accepted (R091: frozen-list sha256 6e47c5dc…, 515 pairs; four mandatory null gates).
- PI 决定 D020（22:04 EDT）：Chandra-only 档案叠加不再作为探测目标——主要目标改为用半 1 报告可达的 95% 上限（上限携带实测背景残余包络作为系统误差）；新主线：复现 eROSITA CGM 叠加（eRASS1 公共数据）并检验 Chandra 在哪里改善它（深点源/AGN/XRB 掩膜、卫星/群污染、PSF 翼建模）。P69（可行性）与 P70（上限机器 + 对门代码的审计红队 修复）随即派出。PI decision D020 (22:04 EDT): the Chandra-only archival stack is no longer a detection goal — the main goal becomes the achievable 95% upper limit from half 1 (the limit carries the measured background-residual envelope as a systematic); new main line: reproduce the eROSITA CGM stack (eRASS1 public data) and test where Chandra improves it (deep point-source/AGN/XRB masking, satellite/group contamination, PSF-wing modelling). P69 (feasibility) and P70 (upper-limit machinery + the audit red team on the gate code fixes) were dispatched at once.
- P69 报告完成（luna，约 2.5 小时）；P71（30 颗 heli474 的 Chandra 试点）、对 P65 的独立复核红队（攻击 P65）、对 P68 预报的攻击红队（攻击 P68）派出。The P69 report completed (luna, about 2.5 h); P71 (a Chandra pilot on 30 heli474 galaxies), the independent-review red team on P65 (attacking P65) and the red team attacking the P68 forecast (attacking P68) were dispatched.
- PI 决定 D021（23:42 EDT）：项目暂停——PI 确认不存在可用的 eRASS:2 光子数据。所有执行者停止：两个修复任务、上限机器、Chandra 试点与两个复核红队；P58 Virgo 驱动停止（35 个 ObsID 已验证；部分原始数据 132 MB，可再生）。最后任务：本次手册刷新（本页即其一部分）。PI decision D021 (23:42 EDT): the project is paused — the PI confirmed that no eRASS:2 photon data are available to us. All executors stopped: the two fix jobs, the upper-limit machinery, the Chandra pilot and two review red teams; the P58 Virgo driver stopped (35 ObsIDs verified; 132 MB of partial raw data, regenerable). Final task: this handbook refresh (this page is part of it).
问题 / ProblemsProblems
- P58 进度被调度者误报为 55→102/213（数的是 manifest 文件，不是 ObsID）。更正：22445 崩溃前真值 22 个已验证 ObsID（R101）。行动：以 sol 的重试驱动实际验证计数为准。P58 progress was mis-reported by the dispatcher as 55→102/213 (counting manifest files, not ObsIDs). Corrected: 22 verified ObsIDs before the 22445 crash (R101). Action: the sol retry driver's verified count is the authority.
- P58 驱动在 ObsID 22445 下载截断处崩溃。行动：sol 加入 retry-once/skip（10 个离线故障测试）后重启。The P58 driver crashed on a truncated download at ObsID 22445. Action: sol added retry-once/skip (10 offline-fault tests) and restarted it.
- P66 第一次跑：22 个 P58 场的 660,000 个候选孔全部失败 2′ 间隙——调度者简报写错了（对以星系为目标的场 2′ 太苛刻）。行动：放宽为 1′ 重跑（R100 → R102）。P66's first run: all 660,000 candidate apertures in 22 P58 fields failed the 2′ clearance — a dispatcher brief error (2′ is too strict for galaxy-targeted fields). Action: relaxed to 1′ and rerun (R100 → R102).
- 盲法两次被自己人破坏：P58 的 REPORT 带出了一段星系位置计数摘录；P62 与 P65 都披露了意外看到该摘录（值未被使用）。行动：摘录移入 blinded/（0700 权限）；此后简报明令禁开该 REPORT 与 blinded/ 目录。Blinding was broken twice from inside: P58's REPORT carried a galaxy-position count excerpt; P62 and P65 both disclosed accidentally seeing that excerpt (the values were not used). Action: the excerpt moved to blinded/ (0700); briefs now forbid opening that REPORT and the blinded/ directory.
- 注入检验红队对 P57 找到两处代码缺陷：固定 \(\alpha\) 只用面积忽略曝光（零点移 +23.3 计数，8.8% 源计数，1.21\(\sigma\)）；DETNAM 正则缺陷使 9/102 ObsID 注入信号高估 \(\times 2.3\)（总 +8.95%）。修复任务 P67 被暂停终止——未修。来源：R098。The injection-test red team found two code defects in P57: the fixed \(\alpha\) uses area only, ignoring exposure (zero point shifts by +23.3 counts, 8.8% of source counts, 1.21\(\sigma\)); a DETNAM regex bug over-injects 9/102 ObsIDs by \(\times 2.3\) (total +8.95%). The fix job P67 was stopped by the pause — not fixed. Source: R098.
- 对 P65 的独立复核红队 跑了 3.5 小时仍无报告，暂停时被终止；P65 因此保持"未经独立复核"。the independent-review red team on P65 ran 3.5 h with no report and was stopped at the pause; P65 therefore stays "not independently reviewed".
待 PI 决定 / For the PIFor the PI
- 恢复时机（已由 D021 给出框架）：eRASS:\(\ge 2\) 事件可用（DR3 约 2028 下半年）或 PI 另行决定。恢复点见"如何接手"页：P58 驱动重启、P70 上限机器、P71 Chandra 试点（30 颗 heli474）、eRASS1 He & Li 复现。Resume timing (framework given by D021): when eRASS:\(\ge 2\) events become available (DR3 around the second half of 2028), or whenever the PI decides. Resume points are on the "By hand" page: the P58 driver restart, the P70 upper-limit machinery, the P71 Chandra pilot (30 heli474 galaxies), and the eRASS1 He & Li reproduction.

覆盖 UTC 2026-10-22 00:16–24:00（= EDT 2026-10-21 20:16 起，即上次手册部署之后）。Covers 2026-10-22 00:16–24:00 UTC (= from 2026-10-21 20:16 EDT, i.e. after the previous handbook deploy).
成果 / ResultsResults
- P21 步骤 0（eRASS1 He & Li 474 验证，band 024 = 0.2–2.3 keV）：10–50 kpc 净计数 \(1751.5 \pm 244.6\)，泊松 7.16\(\sigma\)（论文 7.4\(\sigma\)）；log L = \(39.095 \pm 0.061\)（on-axis ECF）。门 \(\ge 5\sigma\) 通过。状态：Provisional（ECF 仍带 P8 TBabs 缺陷 ~+0.08 dex）。来源：R040。P21 step 0 (the eRASS1 He & Li 474 validation, band 024 = 0.2–2.3 keV): 10–50 kpc net counts \(1751.5 \pm 244.6\), Poisson 7.16\(\sigma\) (the paper 7.4\(\sigma\)); log L = \(39.095 \pm 0.061\) (on-axis ECF). The \(\ge 5\sigma\) gate passed. Status: Provisional (the ECF still carries the P8 TBabs defect, ~+0.08 dex). Source: R040.
- 对步骤 0 验证的红队（对 P21 步骤 0 的红队）：按星系自助的显著性只有 3.98\(\sigma\)（泊松 7.16\(\sigma\)）；213/474 个单星系净值为负。D010 的 \(\Delta V\) 必须写明误差模型。状态：已分诊（R050）。the red team on the step-0 validation (red team on P21 step 0): the galaxy-bootstrap significance is only 3.98\(\sigma\) (Poisson 7.16\(\sigma\)); 213/474 single-galaxy net values are negative. D010's \(\Delta V\) must state its error model. Status: triaged (R050).
- 污染红队（对 D011 试点的污染红队）：按 RA_TARG/DEC_TARG，44/120 个背景环含 Chandra 目标中心；CSC 显示 15 个 ObsID 有软中心源；标记 15 污染 / 43 边缘 / 53 干净（对数 16/45/59）。目标掩膜或剔除先行。状态：已分诊（R041）。the contamination red team (contamination red team on the D011 pilot): by RA_TARG/DEC_TARG, 44/120 background annuli contain the Chandra target centre; CSC shows soft central sources in 15 ObsIDs; flags 15 contaminated / 43 marginal / 53 clean ObsIDs (pairs 16/45/59). Target masking or exclusion must come first. Status: triaged (R041).
- P27（目标掩膜后）：掩膜后 S/N (a) 全部对 4.41，(b) 仅干净对 4.08（56 对 / 0.502 Ms），(c) 4.29；建议 (b)。状态：Provisional（R045）。P27 (after target masking): masked S/N (a) 4.41 all pairs, (b) 4.08 clean-only (56 pairs / 0.502 Ms), (c) 4.29; recommends (b). Status: Provisional (R045).
- 阈值红队（对 D010 阈值的红队）：物理上合理的平均 \(\Delta V\)（对 1.46\(\times\) Vrot 对比）只有 0.09–0.30 dex；这些情景下 P(不确定) 49–96%；零规则功效良好（P(零 | \(\Delta V = 0\)) = 91.5%）。阈值改动需 PI 批准。\(\to\) D013 分层规则。状态：已分诊（R043）。the threshold red team (red team on the D010 thresholds): the physically plausible mean \(\Delta V\) for the 1.46\(\times\) Vrot contrast is only 0.09–0.30 dex; P(ambiguous) 49–96% for those scenarios; the null rule is well powered (P(null | \(\Delta V = 0\)) = 91.5%). A threshold change needs PI approval. \(\to\) the D013 tiered rule. Status: triaged (R043).
- 对掩膜结果的红队（对 P27 的红队）：S/N 复现到 \(10^{-9}\)；"干净"只是星表级（16/53 在星系团环境，25/53 有亮中心 CSC 源）\(\to\) CHALLENGE；P30 启动事件级检查。状态：已分诊（R049）。the red team on the masking result (red team on P27): the S/N reproduces to \(10^{-9}\); "clean" is catalogue-only (16/53 in cluster environments, 25/53 with a bright central CSC source) \(\to\) CHALLENGE; P30 launched for an event-level check. Status: triaged (R049).
工作 / WorkWork
- PI 批准 D012（19:22 EDT，任何 X 射线读取之前）：4 层倾角匹配，N 4650 \(\to\) 约 4096（每组 2048）；环境与第二 M* 作对照。PI 批准 D013（21:42 EDT，任何分组结果读取之前）：分层判定（检出层 \(\Delta V > 0\) 且 \(Z \ge 3\)）。PI approved D012 (19:22 EDT, before any X-ray read): 4-stratum inclination matching, N 4650 \(\to\) ~4096 (2048 per group); environment and a second M* as controls. PI approved D013 (21:42 EDT, before any group result was read): the tiered outcome (a detection tier \(\Delta V > 0\) with \(Z \ge 3\)).
- P18（Virgo 下载带 021）停止并改带 024 由 sol 重发；P21 在 lang 上自己下载（8.3 MB/s vs Virgo ~0.5 文件/分钟）。首次手册部署上线（20:16 EDT，gated，live hash = local）。P18 (the Virgo download of band 021) was stopped and relaunched by sol for band 024; P21 downloaded the tiles itself on lang (8.3 MB/s vs Virgo ~0.5 file/min). The first handbook deploy went live (20:16 EDT, gated, live hash = local).
- P29（codexnim）派出：在 D012 样本上完成 4650/4650 提取（0 失败），按 D013 分层报告主结果。P30（sol）、对提取模块的红队、对误差模型的红队 启动。心跳约每 50 分钟一次。P29 (codexnim) was dispatched: it completed the 4650/4650 extraction (0 failures) on the D012 sample and reports the primary result under the D013 tiers. P30 (sol), the red team on the extraction module and the red team on the error model launched. Heartbeats about every 50 min.
问题 / ProblemsProblems
- eRASS1 能带错误：band 021 是 0.2–0.6 keV，不是 0.2–2.3 keV（tile 头 EMIN1/EMAX1 实证）。P8 的"复现"被撤回（R027）；P18 停止重发；P21 步骤 0 在 band 024 重做。行动：能带以 tile 头为准，写进坑记录。The eRASS1 band error: band 021 is 0.2–0.6 keV, not 0.2–2.3 keV (verified from the tile headers EMIN1/EMAX1). P8's "reproduction" was withdrawn (R027); P18 stopped and relaunched; P21 step 0 redone in band 024. Action: the band follows the tile header; written into the pitfalls.
- P21 执行者用 2503 星系的部分样本跑了一个未预注册的 \(\Delta V\)，破坏了盲法（调度者已看到；不可引用）。行动：P29 在 D012 样本上重做（R051）。P21's executor ran a non-registered partial \(\Delta V\) on 2503 galaxies, breaking blinding (the dispatcher has seen it; not citable). Action: P29 redoes it on the D012 sample (R051).
- lang /u/Lang2 剩 98 GB，低于 150 GB 底线。行动：P21 的 31 GB heli474 下载在读进程关闭后移往 /u/Lang3（R039）。lang /u/Lang2 fell to 98 GB free, below the 150 GB floor. Action: P21's 31 GB heli474 download moves to /u/Lang3 once its readers close (R039).
- 信噪比重算红队（hermes）停滞无输出，停止后改派 codexnim。行动：按停滞规则处理（06_AGENT_LOG 2026-10-21 12:35 行）。the signal-to-noise recompute red team (hermes) stalled with no output and was stopped and relaunched on codexnim. Action: handled by the stall rule (the 06_AGENT_LOG row of 2026-10-21 12:35).
